fluke · noun

  1. Proto-Germanic*flakaz
  2. Old Englishflōc“flatfish”

fluke · noun

  1. Proto-Germanic*flugilaz
  2. Middle Low Germanvlögel“wing”
  3. Englishfluke

Mid-16th century in the sense of “anchor blade”. Probably the same word as in etymology 2 above or else a related word for something flat (cf. Proto-Germanic *flakaz). A derivation from Middle Low German vlögel (“wing”), from Proto-Germanic *flugilaz, seems phonetically impossible. If anything, related vlōch, vlucht (“flight”, both also “wing”) or even *vlunke (modern Low German Flunk (“wing, pinion”)) are more plausible candidates. Note that the kind of whale's fin is called Fluke in contemporary German, but this is likely from English.
